Low-temperature copper-aluminum flux-cored welding wire

Copper aluminum welding rod features:

1. Excellent Welding Quality: Made by a reputable manufacturer, as you can see from the pictures, the welding rod is smooth and shiny. The welding results are full and glossy! It comes with flux inside. It features a low melting point (about 420℃), good fluidity, strong tensile hardness, and good sealing. No need for additional flux, either.

2. Direct Use: No soldering paste required, open and use! Super convenient! Easy welding.

3. Simple Usage: First, sandpaper the welding area of the copper and aluminum pipes (must clean off any paint, oxides, oil, etc. on the metal surface), then move the welder and uniformly heat the area to be welded. When the temperature reaches about 420℃ (medium temperature), add copper-aluminum welding wire to melt and uniformly flow into the bonding point. Once the weld seam is full, remove the welder and let it cool. No further treatment is needed after cooling. The flux residue is visible but non-corrosive, moisture-proof, and firmly attached.
